Description

用於檢測供電動交通工具用之充電站之能源量的裝置與方法
本發明係關於用以檢測被傳送至電動交通工具之電氣能源的方法與裝置。
所謂的“電錶”是習知地用以檢測所傳送的電氣能源量或電功。用於家庭中付帳消耗之這型式的電錶檢測供電網路之中所供應的相位電流並且同時也檢測被供應之電壓。因此，它們藉由隨著時間的相乘及積分之方式而決定單位千瓦小時之瓦特能源量。
最常見的是，依據感應原理操作之所謂的“法拉利斯儀錶(Ferraris meter)”。其中，在一鋁盤中利用單相或多相電流以及網路電壓被感應之一轉動磁場，該轉動磁場藉由渦電流在這鋁盤中產生一扭矩。這扭矩是成比例於電流及電壓之向量積。該鋁盤在由一永久磁鐵所構成之渦電流制動器中運轉，而產生與速度成比例之一制動力矩。該鋁盤，可自外面經由一窗口看見其之邊緣，因此具有成比例於電氣實際功率之轉動速率。一鼓輪計數器連接到該鋁盤，因而能源總量可作為千瓦小時(kWh)之數值被讀取。
對於付費客戶，例如，在私人家庭中，具有二個及更多個計數器之這類型的機電能量儀被使用，以便能夠以時間相關之方式發出不同帳單。在這些計數器之間的切換，例如，藉由內建式接收器或藉由能源供應公司之中心漣波控制系統所控制的外部漣波控制接收器被執行。因此，能 源消耗可對於在較低網路負載時間(例如，在夜間)之消費者以較低的價格計價。
數位電子能源儀錶(所謂的"智慧型電錶")，其不包含先前習知之任何機械式移動元件。其電流藉由，例如，具有軟性環狀磁心之電流轉換器，或藉由具有分流器或霍爾(Hall)元件之羅格斯基(Rogowski)線圈之電流量測系統而被檢測。能源計算經由電子電路進行。該結果被傳送至由字母與數字符號構成之顯示器，例如，液晶顯示器(LCD)。這型式之數位電子能源儀具有遠距讀取能力之特定優點，並且因此使得至今習用的年度讀取成為非必要的，因儀錶資料電氣式地被發送至電力供應商(例如，經由網際網路)。
各種變化可被使用作為資料界面，例如，紅外線、SO界面、M-匯流排、無電位接點、EIB/KNX、或電力線載波(PLC)。
這型式之能源量儀錶同時也被使用在電動交通工具之充電站中作為分別地構成之裝置，以便檢測且讀取饋送進入交通工具電池之能源量。更進一步地，充電站具有一監控裝置以便確保其之適當操作並且，如果適合的話，以便於充電站超載情況中引入適當的保護措施。為了提供適當的信號給監控裝置，用於電流或功率檢測之另外感知器通常被提供於充電站中適當位置。在由多數個充電站構成之系統的情況中，就量測技術而論，會特別需要用到相對較高的花費。
因此，本發明目的是開發上述型式的一方法或一裝置，以便使充電站之操作可靠度的監控更具成本效益。
於用以決定在電動交通工具充電期間傳送能源量之方法的情況中，其目的藉由下面的特點被達成：將電動交通工具連接至一充電站而用以得到被提供在充電電纜線上之電氣能源；在欲充電的期間內，將所需的能源量饋送進入該電動交通工具之一電池；檢測由一能源量儀錶針對能源量之計算所需的至少一個電氣數值；並且將該能源量儀錶計算能源量所需的該至少一個電氣數值輸出至一監控裝置，以供用於該充電站的操作監控。
目的同時也藉由用以決定在一充電站中對電動交通工具充電時之傳送電氣能源量的一裝置而被達成，該裝置具有下列特點：具有用於檢測施用於一能源供應網路的充電電路中之電氣數值的檢測構件，所述電氣數值尤其是指電壓和電流；具有用於自至少一個檢測到的電氣數值計算能源量之計算構件；具有用於該被計算出的能源量之一第一輸出構件；以及供用於將該至少一個另外的電氣數值輸出至一監控裝置以供用於該充電站之操作監控之一另外輸出單元。
本發明具特徵於，除了能源量輸出至例如一顯示裝置或能源供應商之中央帳務部門之外，饋送進入電動交通工具電池之電量儀錶還可提供至少一個另外的電氣數值，作為用於充電站之監控裝置的一輸入信號。由於這電氣數值總之被使用於能源量計算且因此出現在能源量檢測裝置 中，諸如電流轉換器或量測電子器材之另外的構件可被省略，因此就用於充電站保護概念之改進的量測技術方面而言，花費可相當大地被降低。
較佳地，本發明提供：進行「將能源量計算所需的至少一個電氣數值輸出至監控裝置」，以用於充電站之操作監控，其中該監控裝置最好是包含一保護裝置以供防護充電站之相位電流。因此，充電站或用於一群充電站之保護概念可進一步地被簡化。
依據本發明之另一組態，提供：用於能源量計算所需的至少一個電氣數值，是被分配至分別相位的相位電流及/或相位電壓及/或實際功率。
供用於監控裝置所需的電氣數值(相位電流、相位電壓、相位實際功率)最好是經由一資料界面被提供，其中這界面被作為一分別界面或與該界面一起供用於計算能源量之輸出。
最後，本發明之另一論點同時也包含能源量之量測裝置的使用，就該量測裝置本身而言，其是習知地供用於監控電動交通工具之充電站的操作可靠度。
為此目的，習知為“電錶”之裝置將僅被修改，以便提供所需的進一步電氣輸出數值以供用於監控裝置中之進一步的處理。
圖式簡單說明
接著，將依據展示實施範例的圖形更詳細地說明主題。於圖形中： 第1圖展示依據實施範例之分解結構圖；第2圖展示依據第1圖展示之實施範例之用於能源量儀錶的細節。
第1圖展示一交通工具2，其可以是純粹之電動交通工具或混合式之交通工具。該交通工具2具有一電池4及一充電控制裝置6。更進一步地，交通工具2具有一儀錶8(例如經校準之計數器)。電池4經由充電裝置6以及儀錶8經由電纜線10連接到充電站12。充電站12具有插座14且同時也具有儀錶16。儀錶16連接到能源供應網路22。
第1圖進一步地展示之另外的消費者24可被附至儀錶16，其相似地經由儀錶16自能源供應網路22而得到電力。
在交通工具2或交通工具2之電池4經由電纜線10充電的期間，電流自能源供應網路22經由儀錶16以及插座14而流動，並且同時也經由電纜線10、儀錶8以及充電裝置6進入電池4。
儀錶16計算流入電池4之能源量以及消費者24所得到的能源量。
如自第2圖所見，在輸入端上，亦即在其面向能源供應網路22之連點上，儀錶16具有供用於被施加至這量測點的相位電壓之第一檢測器31，並且同時也具有供用於流進儀錶16之相位電流的第二檢測器32。檢測器31、32被構成如習見之供用於對應電氣數值之檢測器，亦即，例如，環形蕊心電流轉換器，霍爾感知器，等等。在自檢測器31、32 之輸出信號的某一時期上傳送之能源量被計算並且這可被顯示在儀錶16之顯示裝置33上。
儀錶16是一種遠距讀取儀錶，其經由通訊網路18連接到一帳務中心20。通訊網路18可以是能源供應網路22之部份，因而一通訊，例如，可利用電力線通訊經由能源供應網路22而進行。通訊網路18同時也可以是有線或無線的通訊網路。例如，一IP協定可被使用於通訊。
在輸出端上，儀錶16不僅具有供用於計算能源量之輸出單元34，同時也具有供用於經由檢測器32被檢測之相位電流的另一輸出單元35。該另一輸出單元35可直接地輸出檢測器32之量測數值或從該處導出之另外處理信號。此外，相位電壓或檢測器31之對應進一步處理信號也可利用另一輸出單元35被輸出。最後，共同自檢測器31及32之信號導出的輸出信號之另一輸出單元35的輸出，尤其是相位實際功率，也是可能的。
供用於量測能源量之資料界面36被分配至另一輸出單元35以及至輸出單元34，其中這資料界面可分別地被構成，或與供用於能源量的資料界面一起被構成(如第2圖之展示)。
相位電流或另一電氣信號是可經由資料界面36而用於進一步處理。該進一步處理發生於具有確保分別充電站之操作可靠度目的之監控裝置中。為達此目的之相位電流檢測器所需的進一步功能性被給予而不需另外的花費。亦即，其可省掉額外的電流轉換器以及相關的量測技術構 件，因為這些已呈現在儀錶16中。
對於由多數個充電站構成之系統，分別充電站中之分別的相位電流可以此方式分別地被監控，並且以此方式，一共同保護概念可被建立而不需供用於檢測器或必須的信號檢測以及調整之另外花費。
於此情況中，該監控裝置可連接到一保護裝置，藉由此方式，充電站將相對於可能之超載而受保護。為此目的，對於分別相位電流之量測數值在預定時間部份之內自儀錶16經由資料界面36被發送至保護裝置並且在達到臨界觸發數值事件中，適當的充電站保護功能被致動。
另外地，或除了相位電流輸出之外，量測數值之輸出可發生以供用於相關相位中之電流實際功率。這量測數值同時也可經由一分別或共用的資料界面被發送以供用於進一步的處理並且形成供用於充電站之監控裝置及/或保護裝置之一輸入數值。
